' My present improvements are here shown "applied to a beater having substantially parallel beater blades land 2' supported on a wire' 3; that is bent tosubstant'ially- U-shape the extremities of the wire 4 passing loosely V through the upper ends of the heaters 5 and passing-loosely through the pinions 6.

shown at 8, which forms vertical parallel portions 9-and end horizontal portions 10.

'Thusfar we have explained the ordinary construction of a beater.

In carrying out'my present improvement the parallel portions 9 of the U-shaped part 7 8 are provided with openings 11, and the ends 12 jofg the wire 3 extend upward beyond the pinions 6, the upper ends13 of theends 12 being bent laterallyand passing through the said openings. 1 a This construction serves a triple function in that when applying the wire 3 to the supporting frame 7 the-laterally bent ends 13 serve to position the wires properly in respect tothe frame so that thebeaters 1 and Qare always assembled proper relation to correctly operate. Another object of the laterally bent ends passing-through the openings of the supporting frame is that their upper ends are held against lateral in proper positionso that they can be spot welded to the vertical porting frame. T

' The wires, having their ends placed in the said openings and the blades being assembled on the wires with theirpin'ionsfi, a spot weld is made between the ends 12 and the parallel portion 9 at a point between the pinions and'thelaterally turned ends 13.

Preferably the spot weld is made at about i the points 14;. In making a spot weld, the

1 fmetal, as well understood, is somewhat distorted since it isbrought to a welding heat andthen pressed by the :welder and the current cut'ofl" when the weld is'completed.

The weld is 'quickly made, and is together "with thelaterally' bent ends of the wires effective in holding them rigidly in their posithe supporting wires.

portions 9 of the supg pears a'still furthermodification of the manwires may be placed at the innersides of the parts 9 of the. support ng frame, in

which event the ends 13 will be turned out-V ward instead of inward, and in that event the weld is made in substantially the same manner as when the wires are outside. The

reversal of the wires will be readily understood so'that it is unnecessary to show them in the reversed positions. I

I desire it understoodthat' changes may be made 1n the presentimprovement without departing from the scope of the invention,

so long as the change is within the scope of the appended claims.

Some of the changes which might be read- 11y made 1n the present invention are set forth in Figs. 4 to lS inclusive, the detailed description of which follows hereinafter.

' Referring to Figures 4 to (Sinclusive, particularly, which show a modified form of attaching the beater blade supporting wires be seen that there is here utilized the same supporting frame 7 having a U-shaped por tion, the vertical walls of the U being designated by the numeral 9. There is also uti- 3, the upper extremities of which are designated by the numeral 1; The vertical walls 9 of the supporting frameare providedwith openings which receive inturned' ends 13 of ings the walls 9 are provided with vertical grooves or channels 15 which receive the upper extremities ofthe wires. 3 and aid in preventing laterahdisplacement of them. To circumvent any possibility of displace ment in any. direction, the wires are spot welded as at 16 .and thus rigidly held in the channels or grooves 15. This weld is made inthe inner side of thewalls 9, or more to the beater blade supporting frame, it will lized the same beater blade'su'pporting wire Below these openaccurately, from the inner sides of the chain nels 15. a p

This frame is likewise provided with the channels. or grooves 15 for receiving and guarding the upper ends 4 ofthe supporting wires from lateral displacement. The supporting'ends 20 adapted to receive between them the supporting wires 3. To definitely and firmly clamp the supporting wiresin place in the supporting frame channels these ears. are

bent towards one another, as clearly ap pears in dotted lines at 21 in Figure 10 of the drawings. It will be seen that'these ears when bent, definitely engageand crimp over the supporting wires, thus securing X them against displacement.

I ing the operating handle 25.

In Figures 11 to 13 inclusive, there appears a still further modified form of attaching the beater blade supporting wires to the beater blade supports.

In this instance the beater blade support is of a slightly different construction, com-i prising two vertical members 22 and 23 in parallel spaced relation and supporting between them the driving gear wheel 24 carry- I Adjacent their lower ends the beater supporting arms 22 and 23 are bent outwardly as at 26 while their lower ends terminatein elongated outwardly extending ears 27 below which are "mounted the beater blades 28 superimposed by the pinion gears 29. l c

The beater blade supporting wires are similar to those heretofore described and provided with upwardlyextending ends 4 theaextrem-ities; :of' which; 'are bentiinwardly tov pass-through suitable openings 11 inuthe' arms 22 andv 2,3. so that. theirinner ends pene+ trate these; arms as clearly;- appearsrat31'3- When the supporting-wires have beenpositl-OIlQCluSO: that-their inturned-ends areextending through the?openingsfll the out wardlyextending ears-.27 arefbent over and clamped;Jfirmlyjdown upon. the upper/ends tofizthe wires; as clearly appears at 30,. each ear asuming a semi-circularform and guards ing: the. wires displacement f and" any porting armss22 and 23,.
